Apologies for the delaying of the demo release that was initially planned some time ago. This is an initial release for the chapter 24 demo. The software implements a basic single tasking operating system; supporting executing user mode 32 bit PE images in separate address spaces. Chapter 24 provides the framework for implementing complete multitasking that we will look at in the next chapter. Chapter 24 has also been updated to reflect the new layout and additional content that reflects the new demo.
